The Tokyo Outbreak is a biohazardous event that takes place in Japan. The incident occurs simultaneously with the outbreak in Raccoon City.
In 2002 the T-Virus began to spread in Tokyo; Patient Zero was a young Japanese woman. Her first victim was a nameless businessman she attacked on the street. The virus had rapidly spread across the city and killed countless people. The city, desolated by the outbreak, later became a base of operations for Umbrella and Albert Wesker.
